Hi,
We are using STM32MP157CAA3T processor. We have implemented USB, UART and SD card for Booting purpose.
And currently we are programming the processor via UART8 by using USB to UART convertor.
Used UART4 Debug port for troubleshooting the board.
Problem is that, we are not able to program the board. And also USB, UART and SD card are failing to boot the processor.

Hi @Heena
need to give more details to allow a valuable answer.
I assume it is a custom board.
Did you successfully rebuilt the ecosystem based on your custom HW ?
Is it using STPMIC1 ?
Is it using HSE crystal or oscillator ?
Which DDR ? is DDR tested using DDRFW-UTIL ?
Could you share some console messages ?
Regards
